I think in general you want to use a tool like 'makedepend' or 'gcc -M' instead of trying to write your Makefile dependencies yourself. These track down the headers used by a .c file and output the appropriate Makefile dependency line. I haven't really done this much, but there's a good page of information about it at http://make.paulandlesley.org/autodep.html
